KNX Installing Issue

I am trying to install the KNX integration https://www.home-assistant.io/integrations/knx/ but have issues.

When i press the add integration link it takes to my HA and asks if i want to install KNX. I select yes and a error message comes up

Error

Config flow could not be loaded

I also cant install manually as it does not show in the available integrations

Hi :wave:!
What version of HA (core) are you using?

core-2021.11.5

UI config for Knx was added in 2021.12. I’d recommend updating to the most current version of HA.

Thank you, updating now. I haven’t used HA in a while since I set up what I needed last year
